Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically, but in some species it can be determined due to social, environmental or other factors. For example, Cymothoa exigua changes sex depending on the number of females present in the vicinity.

Overview

The existence of two sexes seems to have been selected independently across different evolutionary lineages (see convergent evolution). The repeated pattern is sexual reproduction in isogamous species with two or more mating types with gametes of identical form and behavior (but different at the molecular level) to anisogamous species with gametes of male and female types to oogamous species in which the female gamete is very much larger than the male and has no ability to move. There is a good argument that this pattern was driven by the physical constraints on the mechanisms by which two gametes get together as required for sexual reproduction.

Plant reproductive morphology

Plant reproductive morphology is concerned with the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.

Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants (green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination process involved both biotic and abiotic interactions. Charles Darwin's theories of natural selection utilized this work to build his theory of evolution, which includes analysis of the coevolution of flowers and their insectpollinators.

Veganism

Veganism is both the practice of abstaining from the use of animal products, particularly in diet, and an associated philosophy that rejects the commodity status of animals. A follower of veganism is known as a vegan.

Distinctions are sometimes made between several categories of veganism. Dietary vegans (or strict vegetarians) refrain from consuming animal products, not only meat but also eggs, dairy products and other animal-derived substances. The term ethical vegan is often applied to those who not only follow a vegan diet but extend the philosophy into other areas of their lives, and oppose the use of animal products for any purpose. Another term is environmental veganism, which refers to the avoidance of animal products on the premise that the harvesting or industrial farming of animals is environmentally damaging and unsustainable.

The term vegan was coined in 1944 by Donald Watson when he co-founded the Vegan Society in England, at first to mean "non-dairy vegetarian" and later "the doctrine that man should live without exploiting animals." Interest in veganism increased in the 2010s; vegan stores opened, and vegan options became available in more supermarkets and restaurants in many countries.

Vegetarianism and wine

Wine is sometimes finished with animal products. Specifically, finings used to remove organic impurities and improve clarity and flavour include several animal products, including casein, albumen, gelatin and isinglass.

Non-vegetarian/vegan additives

Wineries might use animal-derived products as finings. To remove proteins, yeast, and other organic particles which are in suspension during the making of the wine, a fining agent is added to the top of the vat. As it sinks down, the particles adhere to the agent, and are carried out of suspension. None of the fining agent remains in the finished product sold in the bottle, and not all wines are fined.
